UNITED STATES FRED C. BROWN, OF SEATTLE, WASHING-TON.

PORTABLE SELF-HEATING RADIATOR.

Application filed October 20, 1922. Serial No. 595,877.

To all whom t may Iconcer/n Be it known that I, FRED C. BROWN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a new and useful Portable Self-Heating Radiator, of which the following is a specification.

This invention relates to improvements in portable self-heating radiators, particularly of that class wherein the steam generating elements and the radiator body are so combined that the radiator may be readily moved about to any desired room or place, and my said invention comprehends an improved construction of self-heating radiator of the general type mentioned that embodies the peculiar and novel arrangement and combination of parts hereinafter described and specically stated. in the appended claims,

reference being had to the accompanying drawing, in which: v

Figure 1 is a vertical section of my improved self-heating radiator, the parts being shown at their normal or steam generating adjustment.

Figure 2 is an end elevation thereof, the relation of the vaporizing chamber, the water feed and the spraying devices being indicated in dotted lines.

Figure 3 is a detail vertical section on an enlar ed scale ofthe vaporizing mechanism and t e-pressure controlled devices in their shut-off position.

Figure 4 is an enlarged detail horizontalv section of the sprayer, the control valve and the heating element hereinafter mentioned, the valve being shown in the open position.

Figure 5 is a detail sectional view illustrating a modified arrangement of the lever 4o mechanism and the control diaphragm.

The radiator proper may be of any approved. form vit being, in the construction shown i-n the drawing, composed of a plurality of like tubes or units 1-1, the lower ends of which communicate with a bottom extension 2. The radiator body is mounted on end legs 25-25 which, to facilitate moving the radiator to the desired places may, in practice, be equipped with rollers (not shown).

The bottom extension 2 provides a water holding com artment 3 into which the water is entered, t ough a filling vent 4, to the desired level, for example, as shown in Figure 1, by reference to which it will be seen the bottom 30 of thewater holding compartment is inclined on an angle to carry the vwater toward an outlet pipe 5, and forother reasons presently explained.

The pipe 5 extends across from one end of the compartment to the other end. The pipe 5 communicates with a valve controlled chamber 6, with vwhich is joined a spray feeding pipe 7 that extends laterally from the chamber 6, and enters a vaporizing tube or chamber 17 where it terminates in a downwardly directed spray nozzle 70. Nozzle 7 0 directs the water onto a heating element, which element, in the present showing is an electrically energized heating coil 8 mounted in the lower end of the vaporizing tube 17 and whose opposite terminals are connected with a cutout 9 which is adapted for being shut off, simultaneously with the spray water control valve, as hereinafter stated.

10 designates a pressure controlled means for bringing the electrical heating element and the spray devices into action for making steam for heating the radiator and for cutting out the said heating and spraying elements when the steam pressure within the radiator rises above `a predetermined point.

The vaporizing tube or chamber 17, .as is clearly shown in Figure 1, is located adjacent the high end of the bottom 3() and its upperv end extends upwardly above the said bottom to discharge the vapor or steam into the radiator units as indicated on the drawmg.

By projecting the vaporizing tube 17 through the high end of the bottom 30 any tendency of the water to cool the steam as it passes from the tube 17 is reduced to the minimum since the greater part of the water fed into the compartment 3 is carried away from the said vaporizing tube 17.

v The pressure controlled device, before re-4 ferred to, is located at the end of the radiator adjacent the vapor tube 17 and the said device embodies a diaphragm 11 located in a tubular housing 12 which projects laterally from the aforesaid radiator end and the said diaphragm is held to its normal or innermost adjustment by a suitably arranged spring 13, whose tension is such that when the steam pressure within the radiator passes a predetermined point the diaphragm l1 is forced outwardly in the direction of the arrow to thereby shut off the water to the spray nozzle and to cut out the current to the electric heater.

Any suitableiconnections between the diaphragm 11 and the cutout devices for the heater and sprayer may be provided. In the drawing is shown a bell crank' lever 14 pivotally mounted Within the housing 12; having one end thereof joined to the said diaphragm as at 15 and the other end thereof to a link or lever 16 projecting from the housing 12 downwardly and connected at its lower extremity with another bell crank lever 18, pivotally mounted upon the bottom extension 2 and having linked pivoted connection with a valve rod 19 carrying a cutout valve 60 within the valve body (i. From the foregoing it will be readily seen that when the excess pressure of steam within the radiator causes the outward movement of the diaphraginll, the various levers and links above described will changel in position from that shown in Figure 1 to that shown in detail in Figure 3.

20 designates the handle of a control or detent 21 for holding the lever 14 to the water and electric shutoffadjustment when the radiator is not in use.

22 represents the standard type of radiator valve and 23 indicates a safety valve for rethe said connection,

leasing the internal or steam pressure within the radiator if it gets beyond the point that the shutoif control valve devices are set for.

By reference to Figure 5, it will be seen that the lever mechanism may readily be arranged to be hidden from view if desired and a coil spring may be utilized to eXert the desired inward pressure upon the diaphragm. j

From the foregoing description, vtaken in connection with the accompanying drawings, it is thought the complete construction, the manner of its operation and the advantages of my invention will be readily apparent to those familiar with the manufacture and use of self-heating radiators..
